The bq500412 is a Qi-certified value solution that integrates all functions required to
control wireless power delivery to a single WPC1.1 compliant receiver. It is WPC1.1 compliant and
designed for 12-V systems, or 5-V systems with an optional boost converter, as a wireless power
consortium type A6 free positioning transmitter. The bq500412 the surrounding environment for WPC compliant devices to be powered,
safely engages the device, receives packet communication from the powered device and manages the
power transfer according to WPC1.1 specification. To maximize flexibility in wireless power control
applications, Dynamic Power Limiting (DPL) is
featured on the bq500412 when used with an optional boost converter from a 5-V input.
Dynamic Power Limiting enhances user experience by
seamlessly optimizing the usage of power available from limited input supplies. The bq500412
supports both Foreign Object Detection (FOD) and enhanced Parasitic Metal Object Detection (PMOD)
for legacy product by continuously monitoring the efficiency of the established power transfer,
protecting from power lost due to metal objects misplaced in the wireless power transfer field.
Should an abnormal operating condition develop during power transfer, the bq500412 handles it and
provides indicator outputs. Comprehensive status and fault monitoring features enable a low cost
yet robust, Qi-certified wireless power system design.
The bq500412 is available in a 48-pin, 7-mm x 7-mm QFN package.
